aviso. En casa de duda, prevalece el texto inglés.
AVERTISSEMENT Prendre en compte les points suivants, afin
d'éviter toute détérioration électrique,
incendie, dommage aux personnes ou mort:
ADVERTENCIA Riesgo de descarga eléctrica, incendio,
accidente grave o muerte:
Mettre l’alimentation hors tension avant toute intervention sur celle-ci et s'assurer
qu'il n'y a pas risque de redémarrage.
Ne pas ouvrir, modifier ou réparer l'alimentation.
Veiller à ce qu'aucun objet ne rentre en contact avec l'intérieur de l'alimentation
(trombones, pièces métalliques).
Ne pas faire fonctionner l'appareil dans un environnement humide ou dans un
environnement où il peut y avoir de la condensation.
Ne pas toucher le carter pendant le fonctionnement ou directement après la mise
hors tension. Surface chaude risquant d’entraîner des blessures.
Desconectar la tensión de red antes de trabajar en la fuente de alimentación. Evite
una posible reconexión involuntaria.
No realizar ninguna modificación o reparación de la unidad. No abrir la unidad.
Evitar la introducción en la carcasa de objetos extraños.
No usar el equipo en ambientes húmedos. No operar el equipo en ambientes
donde se espere la formación de rocío o condensación.
No tocar durante el funcionamiento ni inmediatamente después del apagado. El
calor de la superficie puede causar quemaduras graves.

EN MLY10.241 Installation Manual
Product Description
The MLY10.241 is a redundancy module for building redundant power supply systems. It is
equipped with two input channels and one output. The two inputs are decoupled by diodes.
Intended Use
This device is designed for installation in an enclosure and is intended for commercial use, such as
in industrial control, process control, monitoring and measurement equipment or the like. Do not use
this device in equipment where malfunction may cause severe personal injury or threaten human
life.
The redundancy module can be used with any type of power supply as long as the maximum output
current ratings are not exceeded. It is suitable for power supplies with continuous overload current
as well as any kind of intermittent (Hiccup) overload behavior.
If this device is used in a manner outside of its specification, the protection provided by the device
may be impaired.
Installation Instructions
Install the device in an enclosure providing protection against electrical, mechanical and fire
hazards.
Do not ground or earth the positive output pole which could prevent redundancy in case of a ground
failure. Ground the negative output pole, when needed.
Use only power supplies with a negligible output ripple voltage in the low frequency range between
50Hz and 10kHz when used in marine applications according to the GL regulations.
Install the device onto a DIN-rail according to EN 60715 with the input terminals on the top of the
device. Other mounting orientations require a reduction in output current.
Make sure that the wiring is correct by following all local and national codes. Use appropriate copper
cables that are designed for a minimum operating temperature of 60°C for ambient temperatures up
to +45°C, 75°C for ambient temperatures up to +60°C and 90°C for ambient temperatures up to
+70°C. Ensure that all strands of a stranded wire enter the terminal connection. Unused screw
terminals should be securely tightened.
The device is designed for pollution degree 2 areas in controlled environments. No condensation or
frost is allowed.
The enclosure of the device provides a degree of protection of IP20. The enclosure does not provide
protection against spilled liquids.
The input must be powered from a PELV or SELV source or an “Isolated Secondary Circuit” in order
to maintain a SELV or PELV output.
Check correct input polarity. The device will not operate when input voltage is reversed.
The device is designed as “Class of Protection III” equipment according to IEC 61140.
The device is designed for convection cooling and does not require an external fan. Do not obstruct
airflow and do not cover ventilation grid!
The device is designed for altitudes up to 5000m (16400ft). Above 2000m (6560ft) a reduction in
output current is required.
Keep the following minimum installation clearances: 40mm on top, 20mm on the bottom, 5mm left
and right side. Increase the 5mm to 15mm in case the adjacent device is a heat source. When the
device is permanently loaded with less than 50%, the 5mm can be reduced to zero.
The maximum surrounding air temperature is +70°C (+158°F). The operational temperature is the
same as the ambient or surrounding air temperature and is defined 2cm below the device.
The device is designed to operate in areas between 5% and 95% relative humidity.
Installation Instructions for Hazardous Location Areas
The device is suitable for use in Class I Division 2 Groups A, B, C, D locations and for use in Group
II Category 3 (Zone 2) environments.
Hazardous Location classification: ATEX: EPS 11 ATEX 1 312 X, II 3G EX ec IIC T4 Gc
WARNING EXPLOSION HAZARDS!
Substitution of components may impair suitability for this environment.
Do not disconnect the device unless power has been switched off or the area is known to be non-
hazardous.
A suitable enclosure must be provided for the end product which has a minimum protection of IP54
and fulfils the requirements of the EN 60079-0.
